JOSEPI-I' RENE.AYOTTE, OF CHICAGO, ILLINOIS.

HAND-moon.

Application filed October 31,-1919.

To all whom it may concern:

Be it known that I, 'JosnPH RENE AYOTTE, a subject of the King of Great Britain, residing at Chicago, in the county of'Cook and State of Illinois, have invented certain. new and useful Improvements in Hand-Tools, of which the following is a specification.

This invention relates to certain improvements in hand tools, such as wrenches and the like. It has been my aim in the development of the invention to devise a tool of the kind described which may be easily operated and applied to parts that are located in relatively inaccessible places; to construct the tool so that it may be readily adjusted to operate most effectively under different contitions; .to provide means for securing to the tool parts which are formed specially to cooperate with other parts that are to be acted upon; and generally to so arrange and combine its component elements in a manner that will produce a strong, durable and adjustable implement. The invention resides further in numerous other features 10f construction and. combinations of parts, all of which willmore clearly hereinafter appear in the specification to follow wherein reference is made to the accompanying drawings which exhibit an exemplification of this invention in the manner following:

Figure lshows in side elevation the .tool with itsoperating handle slightly extended therefrom.

sleeve is formed with lies a washer 19 that and thimble are socket member E that is with a recess Patented Nov. 1, 1921. Serial No. 334,715.

Fig. 12 is a fragmentary view in elevation suggesting an alternative form of external oonfiguration'for the extensible tube; and

Fig.13 is a'seotional detail of the upper end'of a modified operating handle.

eferringparticularly to Fig. 2, it will be noted that the principal parts of the present tool consist of an outer shell or casing A, which surrounds a sleeve B within which is an extensible tube C. At its lower end the sleeve is connected as by means of a universal joint 15 w1th.a:thimble D having an en larged head 16 which presents a shoulder 17 casing which, it will be noted,'may be bent at an angle relative to the main portion of thetool- Any suitable opening 14 may be formedinthe casing nearthe joint 15, as shown, to facilitate assembly and lubrication of the partsinside. At its upper end the a head 18 which overabuts the upper end By these means the sleeve I maintained in a fixed longitudinal position within the casing.

Through the medium of the sleeve rotary motion may be communicated to the thimble which, as will benoted best in Fig. 3, is operatively seated against a plurality of balls of the casing.

20 that, in the construction shown, are socketed in the'walls of is furthermore ada ted the casing. The thimble to receive a tool or adapted to engage with the work, and for this purpose may-be formed interiorly' with polygonal faces and 21 within which is located a leaf. spring 22 secured in place as by means ofa pin 23. The socketmember, which cooperates with the thimble thus formed, is shownto be provided with suitably polygonal faces-24 to fit non-rotatablywithin the thimble, v l V annular groove 25 to receive the hooked end 26 of. the leaf spring. According to this construction, the socket member may he slipped in and out-of the thimble against th'etension of the leaf spring whose normal tendency is'to hold the socket member operatively in position.

In the operation'of the tool, the casing A, which functions as a stationary handle, is held against rotation, its gripping portion being preferably milled or knurled as shown air-27. Rotation of the sleeve B is effectuand is further provided with an ble relation,

ated through the medium of the tube C, which is non-rotatably connected therewith as by means of a pin 28 that is extended through the tube with one end 29 thereof projected exteriorly to lie within a slot 30 that is formed longitudinally of the sleeve. According to this construction, the tube and sleeve are locked in a relatively non-rotatai the tube being free, however, to move longitudinally of the tool as required for purposes of adjustment. To look the tube in a fixed longitudinal position, I have shown a thumb set screw 31 that is threaded into the sleeve head 18 in a manner to "present its acting end. against the tube which may conveniently'be provided at intervals with notches 32 with any one of whichthe set screw may cooperate. Such a notched construction, however, may be modified, if desired, as, for instance, by employing a knurled or milled surface, such as is suggested in Fig. 12.

The upper end of the tube terminates in a clutch head F which overlies the sleeve head, and which is preferably formed with radially disposed slots 33, the number of which, as appears in Fig. 6, ma conveniently be four. Arranged in clutc ing relation to coiiperate with these slots are oppositely disposed lugs 34, depending from the lower end of the tool head G which abuts .the clutch head, vand which is movably con nected therewith through the medium of a fixed tube 35 having its lower end apertured to receive a locking pin 36 which extends through the clutch head as well; the upper end of this tube 35 extends within an axlal bore of the tool head whose walls are formed interiorly with threads 37 projecting therein to cooperate with a threaded plug 38 adapted to be screwed into place against a shoulder 39 below which is a chamber containing a spring'40 which is coiled around the tube 35 presenting one of its ends against a shoulder 41, and its other against a washer 42 which underlies a pin 43 that passes through the walls of the tube in normal alinement with diametrically'opposed openlngs 44'that are formed in the walls of the tool head. According to the construction described, the tool head may be moved longitudinally of the tube 35 against the tension ofthe spring to disengage the lugs 34 from the slots 33 that are formed in the clutch head'so as to permit the tool head to be rotated without communicating its motion to the remaining parts ofthe implement. V

To facilitate operation of the tool, I have provided a handlepin 45 that is adapted'for insertion through opposite openings 46 adjacent theupper end of the tool head; This handle pinmay be of any desired length, and be adjusted lengthwise in the tool head in any selected position. In the accomplish ment of this result, I make use of a friction 49 may be provided to overthe button to confine it in It has already been explained that the tool may be extended longitudinally and, when used, one hand will grip the casing while the other will grasp the handle pin to effect a rotation of the thimble and socket member therein so as to properly cooperate with the work. After imparting to the handle pin a quarter turn, the tool head may be retracted against the tension of the spring 40 to unclutch the lugs 34 from the slots 33 preparatory to reclutching the parts in a different angular relation. It is accordingly unnecessary to shift the position of either hand upon the parts that are grasped.

In Figs. 10 and 11, there is shown a fied connection between the sleeve B and extensible tube C. In this construction, it will be noted that I have provided a cross pin 50 which extends through the tube'C to project both of its ends within slots '51 which are formed longitudinally in the inner walls of the sleeve B so as to lock these parts mo diin a non-rotatable relation to each other.

beyond the upper face of the the tube C and the head Gr may be integrally formed. The walls of this head are suitably apertured to receive a handle pin .55 which is acted upon by a button 56 that is influenced by aspring 57 suitablysocketed within a plug 58 that is threaded within the head in a manner similar to that already explained. While this construction does not provide for clutching and unclutching the to the tube, it nevertheless tool head relative embodies several of the improved features of this invention. I f

The implement that has been herein described'may be constructed to any desired proportions and of any suitable materials.

Changes or modifications may, of course, be made without sacrificing the advantages of this invention, and in respect of all such constructions, in so far as th are defined in the following claims, I desire that they should be included within the scope of this patent.

I claim:
